I know most people will suggest putting together a first aid kit rather than buying one of the prepackaged ones, that's why I would like to take one. I am looking for suggestions for a good list of specific items to put in a ziplock for my thru hike. I do have one I bought in the store but it seems like there are things in it that can be replaced with more useful items for this particular trip. Thank you so much for the advice for a newb.
